Accessing DB2 Unload Data from Multiple Tables

Accessing DB2 Unload Data from Multiple Tables

Multiple table tablespaces result in a single unload file that contains data from several tables.
You can create a data map that can access multiple tables in a single unload file.
You can select individual tables from the unload by using the OBID of the table. The following types of unload files are supported for this type of multiple table access:
  • Type 1 REORG UNLOAD
    The OBID is held in the fourth and fifth bytes of each record.
  • Type 3 DSNUTILB UNLOAD
    The OBID is held in the first two bytes of each record.
Perform the following tasks to create a data map that can be used to access multiple tables in the same unload file:
  1. Add a data map.
  2. Add the underlying tables.
  3. To specify the underlying table for each record type in the data map, enter the appropriate OBID in the
    Record Properties
     dialog box for the DTL__OBID field.
